Octavian, the Child of Calamity who destroyed the Dragon Hunters’ world in the previous cycle; Shenwei and the Barrier Dragon, reborn to save the Winged King; and Ragna and Crimson, who passed their powers to the Child of Calamity and their past selves to change a future destined to end in destruction and resentment... They’ve all come together!
Bound to a System girl made from the Winged King’s soul, Octavian was a Blue Star native in his first life and a Three-Body Earth native in his second. In this life, his memories have been erased, but he will still take the path to supremacy. This time, however, he won’t be manipulated by fate, and will kill the version of himself called Resentment. In Chapter 11, when the protagonist’s power merges with that of the Lich King and future Ragna, his personality changes drastically, and he gains the ability to switch genders!
(The System girl has no memories.) This book has a female lead, but she doesn’t appear until after the first volume. Once the protagonist’s personality changes, his love for all things in the world becomes twisted. This includes, but is not limited to, talking sweetly to his beloved while killing them. As long as they have a soul, Frostmourne can bring them back to life! (The book is also known as The Lich King Rages Across the Heavens Again.)
[Note 1: The story opens during the era of the Winged King, Karura. Since the Ragna manga has not yet concluded, the protagonist may travel to other worlds later. In this book, transmigrators are nothing unusual to anyone except the natives, since similar concepts exist in some worlds. Powerful villains can even create low-level Systems!]
[Note 2: All right, this may actually be a crossover fanfiction set across the heavens, but the title and tags can’t be changed now. To deliver on the strengths of crossover anime fanfiction, as one reader suggested, maybe I’ll add a chat group later (laughs). Planned worlds: Monster Master, Corpse Brother: Ancient Times, Akame ga Kill!, King Exit... and more.]
There are really few fans of Dragon Hunter, and it's rare for someone to write something significant.
